Why it's free to use
- Filed June 24, 1992 and granted August 31, 1993. A patent filed before June 8, 1995 lasts 17 years from grant or 20 from filing, whichever is longer, so its term ended June 24, 2012.
- Any extension is capped at five years, so it can't still be in force.
- We haven't checked its US family, and a later related patent could still be in force. We check US rights only.
